Is there some legislation out which affects adjustable headrests? I know all cars have headrests that adjust up and down, but my old (1996) A4 had headrests that adjusted forward and back, whilst my '07 A6 doesn't. I was in Lincoln Audi the other day and asked one of the salesmen in passing, and he said he didn't know, but yes - all A6's only come with vertical adjustment. I miss having support for the back of my head on long journeys and I can only assume this is because of some safety legislation.

Can anyone shed some light?
